context_page_description: The Xīnmínbǎo Group is a group of geological formations in north central China. They occur across a large depression between the Altai mountains of Mongolia to the north and the Qilian mountains of the Qinghai Plateau to the south, in the Gōngpóquán and Suànjǐngzi basins, and also in the neighbouring Jiuquan Basin.
  Both of these areas are inland basins consisting of fluvial, lacustrine, and intermontane alluvial fan sediments that were deposited during the Early Cretaceous, probably during the Aptian or possibly late Barremian stage, when the climate was semi-arid and subtropical.
  The group has been visited by many expeditions including the Silk Road dinosaur expedition of 1992 which concentrated on the area around Mazong Shan.
